>I do agree with them in requiring proof that 3rd party sellers have a legal right to sell “trademarked” or “branded” products especially for books.
lets say a bookstore goes out of business and I buy their stock and sell it in my own store. Do I need proof that I have legal right to sell those books? First sale doctrine is established law - your discomfort with 'fake' books has nothing to do with anything - no one said anything about counterfeit goods. They're asking them to get some 'proof' they can sell merchandise they bought to sell.
Shopify doesn’t want potential fakes, and many customers like myself are sick of them. My discomfort with shady 3rd party sellers has a lot to do with it because I will take my business elsewhere, or eat up customer support hours and ramp up costs related to returns and exchanges.
It’s a free market. There are plenty of other online platforms to choose from that don’t care whether or not they sell fake garbage. You can also create your own online store if needed.
